thanks heres a few more im just so bad at math How are the coordinates of the new point found if it is rotated 90° counterclockwise? How many degrees is that equivalent to if the rotation is clockwise?

I don't quite understand @seashell 's reasoning. What I believe one should do is find the angle of the point to the \(x\)-axis, and then find the point that is three times the distance away form the origin as the original point.
